Fronius Primo GEN24 3.0 - Dynamic Power Regulation with Several Inverters

"Limit for entire system"
The entire PV system is limited in accordance with a set power limit. The value of
the permissible total feed-in power must be set.
"Total DC system power"
Input field for the total DC system power in Wp.
This value is used if the "Maximum permitted feed-in power of the entire system"
is specified in %.
"Hard Limit"
If this value is exceeded, the inverter switches off within max. 5 seconds. This
value must be higher than the value set for "Soft Limit".
"Soft Limit"
If this value is exceeded, the inverter will regulate down to the set value within
the time required by national standards and regulations.
"Maximum permitted feed-in power of the entire system"
Input field for the "Maximum permitted feed-in power of the entire system" in W
or % (setting range: -10 to 100%).
If there is no meter in the system or if a meter has failed, the inverter limits the
feed-in power to the set value.
Example: Feed-in limitation
(without consideration of the efficiency)
PV system on Fronius inverter: 5000 W
Consumption in home: 1000 W
Maximum permitted feed-in power of the entire system: 60% = 3000 W
Case 1: The battery can be charged
Power at grid feed-in point: 0 W
Power at inverter output: 1000 W
Power into the battery: 3000 W
Case 2: The battery cannot be charged
Power at grid feed-in point 3000 W
Power at inverter output: 4000 W
Power into the battery: 0 W
In this example, no more than 3000 W may be fed into the grid at the grid
feed-in point. However, any loads that are located between the inverter and the
grid feed-in point can be supplied by additional power from the inverter. These
loads are also compensated as required.
Dynamic power

several inverters
Example 1: Fronius SnapINverter ≤ Fronius Primo GEN24
Only one primary meter is required for the Fronius Primo GEN24 inverter.
The power values shown are an example. Inverter configurations with power val-
ues other than those shown in the example are possible, taking into account the
criteria for this example.
